The classical harmonic oscillator is a model system that has a history of more than a hundred years in the scientific literature and that is discussed in every first-year course in physics. Its has achieved the status of a paradigm because it describes the behavior of a wide variety of systems in physics,chemistry, biology, and other fields. To quote Gitterman [1],“In fact, it has been applied everywhere, from quarks to cosmology.” Examples include mechanical systems such as
pendula with small angles of displacement and mass-spring systems, acoustical systems and electric systems such as RLC circuits, as well as man-made devices such as clocks and radio circuits. The prominence and importance of this model stem from the fact that the dynamics of any system in a potential near a local minimum can be approximated by simple
harmonic motion. The harmonic oscillator still holds surprises and remains the object of current research despite its long history. If friction or energy dissipation has to be taken into account,one arrives at the damped harmonic oscillator where the forces are linearly proportional to the displacement from the local minimum and to the velocity
